    摘要:

    [背景] 托光柄菇属(Volvopluteus)隶属于光柄菇科(Pluteaceae),目前世界上仅有4个种。[目的] 调查我国东北地区大型真菌资源。[方法] 采集大型真菌标本,对其形态进行详细的观察和描述,提取DNA,测定rDNA ITS序列,基于最大似然法和贝叶斯法构建系统发育树。[结果] 2019–2020年在吉林省延边朝鲜族自治州敦化市采集的标本中,有6份标本为密执安托光柄菇V.michiganensis,该种真菌此前未在我国发现。在系统发育分析中,采自我国的密执安托光柄菇V.michiganensis与该种的模式标本聚为一个分支。[结论] 密执安托光柄菇V.michiganensis为中国新记录种。

    Abstract:

    [Background] Volvopluteus, a member of Pluteaceae, has only four species in the world currently. [Objective] To investigate the resources of macrofungi in northeast China. [Methods] Samples of macrofungi were collected, their morphology was observed and described in detail. Their DNA was extracted, rDNA ITS sequences were determined, and the molecular phylogenetic tree was constructed based on maximum likelihood and Bayesian inference. [Results] Among the specimens collected from 2019 to 2020 in Dunhua city, Yanbian Korean Autonomous Prefecture, Jilin Province, six V. michiganensis were found, which had not been found in China before. In the phylogenetic analysis, V. michiganensis collected from China was grouped into a branch with the type specimen. [Conclusion] V. michiganensis is a new record species in China.
